How to Print Even and Odd Numbers From 1 to 99 in C#

In this example we will create a simple program to check if a number is an odd or even number.

We use a fairly simply formula

If a number is divisible by 2 with the remainder 0 then the number is an Even number. If the number is not divisible by 2 then that number will be an Odd number.

Example

This shows for loops and uses the modulo operator

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            int i = 0;

            Console.WriteLine("Even Numbers:");
            for (i = 1; i <= 99; i++)
            {
                if (i % 2 == 0)
                {
                    Console.Write(i + " ");
                }
            }

            Console.WriteLine("\nOdd Numbers:");
            for (i = 1; i <= 99; i++)
            {
                if (i % 2 != 0)
                {
                    Console.Write(i + " ");
                }
            }
            Console.Read();
        }
    }
}

This will display the following

Even Numbers:
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88 90 92 94 96 98
Odd Numbers:
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99
